General Instructions

Make sure you measure your space before building. The bed parts can be assembled in the room, so doorways aren’t as big of an issue.


Step 1

Build the Top Bunk

You will need to build a top bunk made up of two footboards. Simple twin size bunk plans are here. When you add the slats to the headers, start in the center and work your way out. If the spacers do not fit tight at the end spacers, don’t despair. Simpy cut a piece of 1×6 leftover from the header to the exact dimension and use it as the spacer instead of the 1×3 spacer.

Step 2

Build the Bottom Bunk For the bottom bunk, you will need to build the Full Size Simple bed, but this time, build two headboards and no footboards.

Step 3

Assembly Measure the location of the top bunk and mark it on the headers for the bottom bunk. Find the center of the marks and drill a 1″ hole, 3″ deep. Then find the center of the bottom of the legs on the top bunk and drill a 1″ hole, 3″ deep. Use 6″ metal headless bolts or hardwood dowels to hold the bunks together through the drilled holes.

Step 4

Ladder For the ladder, cut two 2x4s 64″ long, with both ends cut at 25 degrees off square parallel to each other. Then on the top edge, mark the top edge in 1 1/2″ from the front top corner. Use a square to mark a line perpendicular to the top cut downward. Cut this line off. These are your ladder sides. Measure and mark the ladder sides and screw the rungs to the ladder sides with 2″ screws and glue. The ladder can be attached with metal brackets or by screwing from the inside of the side rails of the top bunk. Guardrail plans area also available in the Twin Simple Bunk Plans.

We are sorry for your disappointment. If you read the entire post, this is how to convert the "simple bed plan" to bunk beds. The plan is the "simple bed" and the post about the full, which also is modified from the "twin simple bed plan"

Hope this helps!

I think I'm going to tackle building this bad boy this weekend.  My question has to do with how sturdy it is. My 4 yr old likes it when I lay down with him before bed.  I'm a good 215 lbs.  I'm concerned that the only thing keepng the top bunk attached to the bottom is four dowels.  For folks who have built this bunk bed, can you tell me if it feels sturdy?  Are you confident the top bunk could support 215 lbs (me) + 50 lbs (son)?

Hi!  I love, love, love this plan and can't wait to use it.  However, the PDF isn't functioning, can you put a new link in?

Replying to myself. It took me a while to figure out this site. (Fire your web designer).

But, here's what I figured out:

1) You need the "Sinple Bed" plan first:…

2) Then you need the "Simple Bunk Bed" plan second:…

3) Then you need the "Twin over Full Bunk Bed" plans here:…, but the .pdf link is broken so use the Printer Friendly version.

How do you get your lumber so cheap? Just ran some quick numbers and lumber alone is near $500 plus fasteners, glue, and finish. $100-150 doesn't seem like a realistic number.
